THOMAS DURRIN, OF SPRING CITY, PENNSYLVANIA.

Specification forming part of Letters Patent No. 185,306,

dated December 12, 1876; application filed May 29, 1876.

To all whom it may concern:

Be it known that I, THOMAS DURRIN, of Spring City, State ofPennsylvania, have invented a certain new and useful Double-Oven Rangeor Cook- Stove; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification, in which Figure l is a perspective view of therange. Fig. 2 is a vertical section behind fire-place. Fig. 3 is avertical section through fire-place. Fig. at is a horizontal sectionthrough ovens. Fig. 5 is a horizontal section below ovens. Fig. 6 is ahorizontal section above ovens.

My invention has relation to an improved double oven portable cookingrange; and consists in the novel construction, arrangement, andcombination of parts, as hereinafter described and claimed.

Referring to the accompanying drawings, A designates a range embodyingmy improvements. B designates the fire-place and grate, occupying acentral position in the front of the range, which extends forward toallow a large cavity, the walls of which embrace the ash-pit as well asthe grate and fire-space.

These protruding walls are made curved or semicylindrical, and areprovided with doors, so that the included space may be completelyinclosed. Directly behind the fire-space are located the ovens O 0,-twoin number, arranged on the same horizontal plane, and separated t'romeach other by a single central partition, B. These ovens extendlaterally considerably beyond the limits of the fire-space, and havetheir doors D upon the ends of the range. The back and front walls, topand bottom of the ovens, are separated from the outer walls of the rangeby spaces or fines a b c d, respectively, all of which are incommunication, so that the heat from the fire may pass entirely aroundthe ovens. F F are dampers to close and open the passages lead ing fromthe top fines to the front and back fines. G G are walls extending backfrom the sides of the fire-space about half the distance toward the backpart of the top fines. H is in the county of Chester and the smoke-fluein the middle of the back part of the range, and I is a dust-fluelocated directly under the central partition B, and leading from theash-pit to the smoke-flue. K is a register to close and open thedust-flue at its forward end. L L are walls dividing the bottom fiueslaterally, and rendering the passages serpentine in form, so as toretain the heatlonger. M M are capscovering openings in the bottoms ofthe ovens, allowing access to the space below for the purpose ofcleaning, 850.

The operation is as follows: When the dampers F are opened the heatpasses back from the tire through the central space N; thence in thedirection of the arrows around the ends of the walls G G, and forward tothe descending flues; and thence underneath and up behind the ovens,escaping finally into the smoke-flue behind the wall E.

To heat only one oven both the dampers over the other oven are closed,when all the heat will be conducted around the first. By closing dampersF and opening dampers F all the heat passes directly to the smoke-fluewithout heating either oven.

Having described my invention, I claim as new and desire to secure byLetters Patent 1. The improved portable cooking-range, having thefire-place in the center of the front, and two ovens behind thefireplace, on the same horizontal line, with doors opening from thesides or ends of the range, and having intercommunicating smoke-tinesabove. below, in front of, and behind each oven, so that the heat shallcirculate around four sides of one or both ovens before escaping,substantially as described.

2. In a portable cooking range, the combination, with the double ovensarranged on a line behind the central fire-place, and sepa rated by acentral vertical partition, ofthe heatlines a b c d, surroundingtheovens, and the dampers F F, located as shown, and for the purposedescribed.

3. In a portable range, the combination, with an oven located back andto' one side of the fire-place, and having flues ab c d to allow theheat to encircle the oven, of the short \vall G,

extending back from the side of the fire-place,

as and for the purpose set forth.

4.1m a portable double-oven range, having have hereunto set my hand this13th day of the fire-place in the center and projecting in May, 1876. Ifront of the ovens, and the smoke-flue in the center of the back, thehorizontal dust-flue, v THOMAS DURRIN' extending from the ash-pit to thesmoke-flue, Witnesses: as shown and described. M. DANL. CONNOLLY,

In testimony that I claim the foregoing I CHAS. F. VAN HORN.
